Twelve 3D arcade games. Real electrical, plumbing, HVAC, safety, and estimating — against the clock. No lectures. Just play.
60 seconds. 5 missions. Find the right breaker in a live 200A panel — before time runs out.
PLAY →480 volts. Run the full lockout/tagout sequence in order. Wrong step = strike. Three strikes, you're done.
UNLOCK →Measure the house, price the cable, pick your margin. Bid too high and the other guy steals the job.
UNLOCK →Six killers hiding on the jobsite. Spot them all before the clock dies. Wrong taps cost you.
UNLOCK →Study the building water layout, then find the ONE main valve in a live mechanical room. Wrong valve = water everywhere.
UNLOCK →Five copper joints, one correct soldering order. Memorize the run diagram — wrong order springs a leak.
UNLOCK →1/4" per foot — or 1/8"? Set four drain segments to code slope from memory. Check your work.
UNLOCK →Rough-in specs memorized? Set the toilet flange, lav drain, and shower valve to IPC heights — from memory.
UNLOCK →Condenser lockout, six steps, from memory. Wrong move = strike. Three strikes and you're shocked out.
UNLOCK →Read the charging chart, then dial in superheat and subcooling on live gauges. Overcharge the compressor and pay.
UNLOCK →Four branches, four sizes. Hang the right duct at every takeoff from the sizing schedule you memorized.
UNLOCK →Five wires, five terminals, zero labels. Land R, W, Y, G, C from the wiring diagram — then call for cool.
UNLOCK →
